If you scrounge electronic components from old equipment, chances are that you have come across parts that couldn’t be identified right away as a transistor or a capacitor or something else. It may be due to a strange shape, an unexpected color coding or the text printed on the part as is often the case with integrated circuits. SMT components may not have any print on it at all. Once a component is identified, you probably want to reuse it. But since it was stripped from an old and possibly defective circuit board, you must verify that it still works before soldering it into your circuit.

In this webinar David Ashton will not only share tips and tricks for identifying unknown electronic components, but he will also present several techniques that can be used to test parts of uncertain provenance without requiring fancy or expensive test equipment.


David Ashton

David Ashton was born in London, grew up in Rhodesia (now Zimbabwe), lived and worked in Zimbabwe, and now lives in Australia. He has been interested in electronics since he was “knee high to a grasshopper.” Rhodesia was not the centre of the electronics universe, so adapting, substituting and scrounging components were skills he acquired early (and still prides himself on). He has run an electronics lab, but has worked mainly in telecommunications.
